Description

technical field [0001] The invention relates to a karaoke on-demand system and a playing method thereof, in particular to a karaoke on-demand system based on a one-way cable digital television network based on a fiber-coaxial hybrid network (HFC) and a cable TV digital set-top box and a playing method thereof. Background technique [0002] As a popular entertainment item, the karaoke function has been deeply rooted in the hearts of the people. Current devices with karaoke functions require bidirectional network support, or require a large-capacity hard disk to store programs locally. How to realize the karaoke function in most basic digital set-top boxes without hard disk based on the one-way cable digital TV network (HFC) will naturally help to attract more users to join the camp of digital TV, thereby promoting the rapid development of digital TV. Contents of the invention [0003] The object of the present invention is to provide a kind of under the one-way cable digit...
